Ask a mountain guide when they take their own holiday and the answer is rarely August. It is the two or three weeks on either side of the season, when the huts are open, the paths are clear and most people have gone home.
What you gain
- Room. The terrace table with the view is free. So is the trail.
- Light. The sun is lower, so the hours either side of midday are worth walking in, and worth photographing.
- Attention. Hut keepers, drivers and guides have time to talk. That is when you hear where to go next.
What you give up
Certainty. The weather is less settled, a high pass may hold early snow, and a few services run a shorter timetable. A good route has a plan B for every day, and a guide who decides at breakfast which one it is.
When it doesn’t work
Some places only have one season. The high Arctic, a desert in midsummer and a reef in the wrong monsoon are not improved by going early or late. For those we go when the place is at its best, and book a year ahead.
How to pick your weeks
Look at when the local school holidays end, then go the week after. It is the simplest rule we know, and it works on four continents.
